This finding not only shows that nano- and micro-sized particles can be included as a new class of building blocks but also means that organization of zeolite microcrystals has been settled down as a field of study in the future of material chemistry(Acc. Chem. Res. 2007, 40, 29–40). He also showed diversity in the field of organization of

. Furthermore, he raised awareness about the importance of organization of micro particles by showing that microcrystals can be synthesized and any axes of microcrystals can be oriented in a certain direction (Science, 2003, 301, 818–821). Yoon developed an innovative method named "Forced Manual Assembly" which significantly contributed to a very simple, time saving, and highly precise organization of nano and microparticles into monolayers on flat
